Patented June 10, 1930 TRIAN BERBEGK, OF BALTIMORE, MARYLAND SAFETY DEVICE Application filed March 2,

This invention relates to improvements in safety devices for airplanes and has for its object to provide a simple and efficient device to be attached to the wings of an airplane so 6 that the latter can travel at a very slow speed if desired or in case of trouble or stopping of the engine. The device can be controlled so that the airplane can be held practically suspended or lowered slowly to avoid accident.

The invention consists of the novel construction and arrangement of the parts and combination of the parts hereinafter more fully set forth in the accompanying drawing and pointed out in detail in the appended 15 claim.

In the accompanying drawing:

Figure 1 is a front view of an airplane showing my device applied to the wings thereof.

Figure 2 is a section on the line 22 of Figure 1.

Figure 8 is an enlarged section on the line 3-3 of Figure 2.

Figure t is a section on the line 4=-l of Figure 3.

Referring to the accompanying drawings forming part of this specification and in which like reference numerals designate like parts throughout the several views thereof, 1 designates an airplane having wings 2 projecting on each side thereof. Secured to each end of the wings 2 and extending therefrom is a projection 3 made of wood or other suitable material and secured to the ends of the wings 2 in any suitable manner. T he projections 3 are provided with apertures a through which the flanged sleeve 5 projects, the said sleeve 5 being held by means of bolts 6 extending through the flange 7 and the projection 3. Within the flanged sleeve 5 is a band 8 and between the band 8 and sleeve 5 are metal strips 9 which form a frame over which the bag or pocket 10 is fitted, the said bag 10 is formed of canvas or other suitable material and fits over the frame 9 but is not secured thereto. Ilhe lower ends of the bag or pocket 10 project down between the band 8 and sleeve 5 and is held securely in position by the bolts 11 which also serve to hold the frame 9 in position. Gn the under surface of the projection is se- FOR AIRPLANES 1929. Serial N0. 343,905.

cured a metal frame 12 projecting under all or the openings 4, the said frame being provided with guides 13 under each of the openings land each of which. is provided a plate 14 which is slidable back and forth. in the guides 13 to open or cut off communication through the openings 4 the bags or pocket 10, also plate ll may be connected by wire cord or other suitable means to be operated by the operator of the machine.

When the machine is flying in the ordinary manner the slides are over the opening l thus closing communication to the pocliets 10. V] hen the operator of the machine desires to run his machine at a very slow sp'eet he can operate the slides or plates 1% to allow air to pass into the pockets l0 and in the event of engine trouble or stopping of the engine the slides may all be operated allowing air to rush into the pockets 10 which said pockets are of surlicient size to operate in a similar manner to a parachute thus holding the plane against a sudden fall and allowin it to descend gradually.

While I have shown my invention applied by means of the projection 3 it is obvious that pockets 10 may be set on the outer edge of the wings of the plane and operated '5. the same manner.

Having thus described my invention what I claim is The combination with an airplane having apertures in the wings thereof, a flanged sleeve projecting through each. of said apertures a band secured to said sleeve. metal strips having the lower ends secured between said sleeve and band, a pocket for each of said apertures, said pockets surrounding the said metal strips and having their lower ends secured between the said sleeves and band, slides arranged below id apertures and means for operating said slides to open or close the apertures to said pockets.

In testimony whereof ll afiix my signature.
